How to get rid of old "unsecured" wireless network

Hi all,
Hope someone can advise.
I have been using a Linksys BEFW11S4 router on an unsecured cable network. Noticing that it was considerably slower in the evenings, I thought that someone was tapping into my account. I went to the web address to change the settings, and made adjustments both to the name of the account, the address just mentioned, and the WEP settings. The new secure network worked just fine. Problem is, the old unsecured "Linksys" network still showed up on the list of wireless networks and was still usable by other computers.
How do I get rid of it and have only the new secure network?
Thanks in advance to anyone who can help!

    Thank you very much for the help.

    Yes, this explains most of it. I had unplugged the Linksys box and used the Ethernet connection for the internet, but the Linksys connection was still showing up. It does appear that the neighbor has an unsecured Linksys account also.

    Only thing it does not explain is why my newly secured wireless connection also seemed to function slowly in the evening. My computer verified that it was connected to the secure connection, so I don't see how another person's account could slow it down.

Are you referring to the Linksys SSID showing up when you browse for available wireless networks? Also, are you in an apartment building or otherwise relatively close to other houses/residents? It is possible that you and a neighbor both have Linksys APs and if neither was secured originally, your neighbor could have been connecting to your AP and vice versa. This definitely would explain slowness especially if you or your neighbor does any type of video or audio streaming.

One way to test this is to shutoff your Linksys router and view available wireless networks on your computer. If "Linksys" still shows up, it is most likely someone else's router/AP.

As long as your SSID shows up and you can only connect to it via the WEP key, your AP is secure.

Let me know if you get different results than I explained above.

    The slowness you're experiencing may be due to the WEP encryption. The following is a link to a throughput test conducted with and without WEP enabled.

    The result was a 50% cut in throughput with WEP enabled. This may be the problem if you are experiencing slowness all the time. If the slowness only occurs at night you may be competing with your neighbor's AP if the APs are using the same channel. Try changing the channel your AP is listening on.

    Good luck.

You have befw11s4 router, which is very old router.
May be you will need to upgrade the firmware of the router.
change the channel to 6.
check the wireless security settings.
Make sure that the wireless MAC filter is disabled.
For this you will need to access the router set up page.
make sure that the computer is connected to the router with the cable when you open the router set up.

My Linksys BEFW11S4 Wireless-B Broadband Router? i cant connect in my internet and my PSP how can i do to connect it?

Set up an open wireless network or with WPA encryption. The PSP supports WEP/WPA but not WPA2 or Wireless G, it's a B device.
Also use a short passphrase and DHCP to lease IP Addresses.

High ping

Question, why are you using so many different routers? Sounds like you are causing a bottleneck in the network.

This is how I have my network.

Modem ---- PFSENSE Firewall (currently my DHCP Server) ------- Cisco Switch ------ Patch Panel ------- out to my Servers, computers and one wireless router. See only one machine is managing my IP addresses.

Buy a patch panel and run wireing to all the locations in the house or just run wireless.

ENET Port issue on BEFW11S4 Wireless Router


Try these steps:

1. Make sure the wireless is disabled when you're doing that. It might cause a confusion between the wired and wireless connection.
2. Try to plug it at other ports (1-4)
3. Try another known working ethernet or CAT-5 cable.
4. Set the laptop's LAN card's speed to 10-hald duplex.

Try these and hope it will help you ;-)

Already tried it..

I can't tell if you tried turning off wireless, HARD WIRING your lap top to YOUR linksys. Did you.

Another way to see if you've done it right, it to turn off your Brother's linksys to see if you can still get onto the internet.

Also are there OTHER wireless routers in the neighborhood? It doesn't sound like you8're communicating with YOU router.

Linksys BEFW11S4-RM 4 port wireless router

This is an old router. Look at the power light. You must have a STEADY power light. RESET the BEFW11s4 by pushing the reset button for 30seconds. Unplug the power of the BEFW11s4 for 30 seconds. Connect pc to port 2 or 3. pc should get an ip of 192.168.1.x. If you are getting this ip that means that the pc is already detecting the router.

Good Day

I would first reset the router to the defaults - Hold in the reset button (a small pinhole on the back of the router) for about 10 seconds and the lights on the front will flash when it resets.

It should enable wireless with a network name called "linksys" and may just start working. If it doesn't you can download the user manual from for help setting it up.

HOpe this helps!
